Transradial Neuroendovascular Treatment for Anterior Circulation Lesions : An Initial Experience with a 6 Fr Guiding Sheath

Objective: To clarify the usefulness and safety of neuroendovascular treatment with a 6 Fr guiding sheath via the right radial artery for anterior circulation lesions. Methods: A total of 20 patients (carotid artery stenting: 11 patients, coil embolization of cerebral aneurysms: nine patients) who underwent neuroendovascular treatment via the right radial artery under general anesthesia, between September 2016 and June 2017, were included in this study. We retrospectively analyzed 1) the pertinent anatomy of the target-side common carotid artery and the aortic arch, 2) devices, 3) method to advance the guiding sheath into the common carotid artery, 4) hemostasis at the puncture site, and 5) outcome (success rate, perioperative complications, and complications at the site of puncture). Results: In all patients, a 6 Fr guiding sheath could be guided into the common carotid artery, and treatment was accomplished. Furthermore, there was no perioperative or puncture-site complication. Conclusion: Transradial neuroendovascular treatment is considered as a safe and successful choice for anterior circulation lesions.
